Portable heater for liquids



NiTED STATES PATENT OEEICE.'

WILLIAM N. lHANCOCK, OF SALEM, NEW JERSEY.

Specification forming part of Letters Patent No. 416,665, dated March 7,1865.

To all whom it may concern Be it known that I, WILLIAMN. HANCOCK,

of the city and county of Salem, in the State of New Jersey, haveinvented a new and Improved Heater for Liquids; and I do hereby ldeclare the following to be a full and exact description of the same,reference being had to the accompanying drawings, making part ot' thisspecification, in which- Figure l is a plan of my improved liquidheaterwith the lid thrown open. Fig. 2 is a vertical longitudinal section ofthe same. Fig. 3 is a vertical transverse section in the line Similarletters of reference indicate corresponding parts in the severalfigures.

My invention relates to an apparatus ot' simple, cheap, and very compactconstruction, especially adapted for the use of soldiers on picket orlike duty for heating coii'ee, water, or any beverage or stimulant. rIhedevice, when in condition for transportation, will occupy a very smallspace, and it is intended to be adapted to be readily carried about inthe pocket of the great coat ot' the soldier.

To enable others skilled in the art to which my invention appertains tofully understand and use the same, I will proceed to describe itsconstruction and operation.

In the accompanying drawings, A represents a vessel ot' any suitablecapacity. The vessel represented is oblong or elliptical in itshorizontal section, but its form may of course be Ivaried to suit thetaste of the user. Said vessel is provided with tubes or iiues, B B, ofconical or other form, occupying' positions over holes in the bottom ofthe containingyessel. In the lid A of the vessel A are holes, throughwhich may escape the products of combustion which ascend through thetubes B.

C is a base or support, the same also constituting a case in which thevessel A may be supported at any height by means of an elastic arm orspring, D, on the lower end of which is a pin or projection, d, to beinserted into either of a series of apertures, c, in the side of thebase G.

In the base C are sockets C for candles, the iiames of which pass upinto the tubes B, and thus heat the contents ofthe vessel A. Instead ofthe candles, I propose to use a small oil-lamp fixed within the base Cin any desirable man- 11er, and, as the size and consequently theheating capacity of such flame may be in v creased or diminished, itwill only be necessary to employ one tube, B, in connection therewith.This method of heating liquid on a small scale will be found expeditiousas well as economical. When candles are used, the vertical adjustmentofthe vessel A within the base O is rendered requisite to maintain anequal degree of heat as the length of the candles diminish. Anycombustible material may be made use of in the absence of candlts orlamps. The candle-sockets C' are adapted to occupy the lower ends of thetubes B when the Vessel A is pushed down until its bottom restsI uponthat of the base O, in which condition the apparatus may be carried withconvenience. By pressing inward the spring D, the pin d may bedisengaged from the side ot' tlicbasc C, so as to permit the positionofthe vessel A to be varied.

The base O has a number oi' openings, c, which may be registered in anysuitable manner to regulate the air which circula-tes through the base Oand prevent the light from" being observed by enemies, when thev deviceis in use by soldiers on picket duty.

A2 is a bail or handle, the application of which is altogether optional.Y

Having thus described my invention, the following is what I claim as newand desire io secure by Letters Patent The combination of the heater A,provided with tubes B, and the base C, provided with sockets C', theheater being adapted to slide up and down within the base and retainedat any desirable height, substantially as and for the purposesspeciticd.

WM. N. HANCOCK.
